Abstract: A disclosed method of operation includes generating a first resolution geographic descriptor that identifies a first size geographic grid area. The first size geographic grid area includes a specific location identified by mobile device location data but does not identify the specific location. The method proceeds with adjusting the first resolution geographic descriptor to a second resolution geographic descriptor, by increasing or decreasing the resolution to correspondingly decrease or increase, respectively, the corresponding geographic grid area to a second size geographic grid area that includes the specific location. An information update is then sent to a server. The information update includes the second resolution geographic descriptor but does not provide the mobile device location data, in order to preserve the mobile device user's anonymity.

Abstract: In embodiments of wireless communication handover profiles, a profile manager is implemented on a communication-enabled device to detect that a signal strength of a wireless connection decreases to a signal-level threshold or lower. The profile manager then monitors the decreasing signal strength of the wireless connection, and compares the signal strength to a handover profile to determine when a handover of the wireless connection from one access point to another will likely occur. The profile manager can then transfer handover parameters to the next access point before the handover to maintain the wireless connection during the handover between the access points.
